XXII EXISTENTIALISM AND SURREALISM, POLITICAL AND RELIGIOUS PHASES One of the main ferments in the literature of recent years and of today is der Existmtialismus. Though ostensibly a break-away from Expressionism it retains some of its main principles; cf. with what follows pp. 359$. Of programmatic Existentialism there are many aspects, simply because the writers classed on broad principles as existentialists interpret exisfatiut (with its etymological roots in ek-sistere] each in his or her own way. The philosophical and religious tenets derive ultimately from the Danish thinker S0ren Kierkegaard (i813-5 5). In Germany the concepts of existentialism have been defined and expounded by the philosophers KARL JASPERS (1883- ) and MARTIN HEIDEGGER (1889- ); both concern themselves with the real Being (Seiri) of self and things, and they seek to eliminate whatever opposition there is between self and things. There is also the very extensive reflex action of foreign existentialists, particularly of the French writer Jean-Paul Sartre with his novel La Nause'e (1938). Since Sartre derives his existentialism from Heidegger and Jaspers the term is obviously philosophical. The essence of its meaning is already woven into the later works of Thomas Mann, Hermann Hesse, and Jakob Wassermann with their mysticized expression- ism, and in the Magic Realism (der maguche lLealismus> die magisck WMichhif] of Georg Heym, Ernst Stadler, Georg Trakl, Hans Carossa and Robert Musil it marks a new stage. The literary programme is best classed as Suma/ism&s, which is taken over from the term surrfalisme coined by Sartte to blazon his decoction of Heidegger; literally interpreted it can only mean Uberwirklichketis- 448
